INTRODUCTION
The model BLACKSIDE-40 sound suppressor is designed to operate
fl awlessly with the majority of autoloading pistols chambered for the .40
S&W cartridge. It is a physically small suppressor for the size cartridge, and
it gains its remarkable effi ciency through the use of artifi cial environment
technology. To better understand this unit, please take a few moments to
read this manual.
This suppressor is capable of reducing the sound level of the .40S&W
cartridge by up to 30 dB through the use of the proper artifi cial environ-
ment. Artifi cial environment is defi ned as a consumable foreign substance
(liquid or paste) inserted into the suppressor to reduce sound by rapidly
absorbing heat from the propelling gases. Completely dry, the suppressor
is hearing safe.
There are a variety of substances which will function well as an arti-
fi cial environment including light oil and automotive grease. Each has its
advantages and disadvantages, which are related to effi ciency, durability,
and smoke signature. Specifi c artifi cial environment materials are dis-
cussed later.
Because of the geometry of most .40S&W handguns, the BLACK-
SIDE-40 by default is provided with the Gemtech Linear Inertial Decoupler
(L.I.D.), which functions as a recoil booster. On special order, it can be
provided with a normal, non-boosted threaded endcap.
